Siak Regency consists of plains and hills with an average soil composition consisting of podzolic red yellow rocks and alluvium and organosol soil and humus gley in the form of swamps or wet gley. United States Department of Agriculture (USDA) that Podsolic Red Yellow (PMK) soil is a soil formed due to too low temperature and very high rainfall and is an ancient mineral soil type with a reddish or yellowish color. This podzolic soil color indicates relatively low soil productivity due to leaching. While the red and yellow soil colors are caused by rusty iron and lumps of aluminum that decompose and undergo weathering. Clay minerals in this soil are dominated by compounds containing silicon, oxygen, and some metals, which have implications for water quality. The purpose of this research is to test water quality to support the fulfillment of sustainable clean water needs in the Swamp Area in Rempak Village, Siak District, Siak Regency, Riau Provonce. The approach method used is Permenkes No. 492/Menkes/IV/2010.The data needed for this research is to use primary data by taking samples of rainwater, well water, and raw water from the Siak river by researchers directly on March 16, 2022. The main results of the research stated that the quality of rainwater was ranked first to support the policies of the National Development Planning Agency towards a just and prosperous Indonesia in 2045 which has mandated the importance of water security to support strategic sectors, disaster prevention, and improvement of community welfare through construction of rainwater harvesting buildings.

With the use of the additive, the clay's shear strength and bearing capacity increased. Usage waste material, Wooden Hush Ash (WHA), is tiny. The silicate content of WHA is almost the same as RHA. This study aims to utilize ASK for a stabilization material of high plasticity clay to increase shear strength. Unconfined Compression Strength (UCS) tests were performed to compare the UCS value of clay; clay with 5% cement; clay with lime; clay-cement with WHA; clay-cement with lime and WHA; and clay with lime and WHA. Before the UCS test, the sample was separated into two groups: with and without curing for 28 days, and with and without soaking for 4 days. While in conditions unsoaked, the qu value is uniform. Results show, without curing and soaked, qu values of all variations have the same value in the range of 350 kPa to 380 kPa. In conditions with curing 28 days with and without soaked, qu values range from 365 kPa to 485 kPa for mixtures with WHA and a combination of lime with ASK. While adding of 10% lime additive increases the qu value to 1100 kPa UCS testing results prove, with and without curing and soaked, lime is more optimal to increase the value of UCS than WHA. Replacement lime with WHA by 4% to 6% increases the qu value from 160 kPa to 465 kPa and 485 kPa and 110 kPa to 440 kPa to 475 kPa of soaked and unsoaked condition respectively. WHA can be used to reduce lime in soil stabilization.

This research is against the background of the large amount of sawdust waste that is not used so that it has the potential to become B3 waste (leakage) due to decomposition. The use of ash from waste incineration such as RHA (rice hush ash), FABA (fly ash, bottom ash) has proven successful in increasing the carrying capacity of clay soils. The combination of ash and cement additives or/and lime, for some cases, also manages to increase the shear strength of the soil. The study aims to utilize sawdust waste ash, WHA (wood hush ash) mixed with cement and/or lime for the stabilization of high plasticity clay. The research method focused on changes in swelling potential and changes in swelling pressure due to the addition of WHA. Several variations of the mixture are made to be able to conclude the best composition of the mixture from these additive ingredients. Sample testing using a Konsolidometer (Oedometer) test kit and swelling measurements by overloading the sample by 1.0 to 5.0 kPa. Samples are printed by compacting using a standard proctor by adding water according to the OMC value of the original soil. The mixture is tested without being muffled and pre-soaked. The swelling test results showed that there was a change in soil type from high plasticity clay (CH) to high plasticity silt (MH). The addition of cement, lime, WHA or a mixture of 2-3 additives is proven to reduce the potential for expansion. The addition of a mixture of additives by 10% reduces the swelling potential to a medium. The addition of lime 10% lowers the swelling potential to Low, while the addition of cement or lime, or WHA of less than 5% does not change the potential to expand the soil. The mixture that best lowers the level of soil development consists of 90% cement soil (95% Clay+5% Cement), 6% lime, and 4% WHA.

Tanah lunak berkaitan dengan tanah-tanah yang jika tidak dikenali dan diselidiki secara berhati-hati dapat menyebabkan masalah ketidakstabilan dan penurunan jangka panjang yang tidak dapat ditolerir, mempunyai kuat geser yang rendah dan kompresibilitas yang tinggi. Peningkatan jumlah sampah yang tidak diikuti oleh perbaikan dan peningkatan sarana dan prasarana pengelolaan sampah mengakibatkan permasalahan sampah menjadi lebih serius. Salah satu cara menangani permasalahan tanah lunak adalah dengan cara stabilisasi. Adapun kajian yang akan dilakukan adalah bagaimana pengaruh abu sampah dalam hal ini berupa abu kayu terhadap stabilisasi tanah lunak di pulau Bengkalis dengan kadar campuran abu kayu yang berbeda-beda dan diharapkan dapat meningkatkan kekuatan tanah serta mengurangi dampak permasalahan sampah yang ada. Selain itu juga digunakan bahan lain sebagai pembanding yaitu kapur (CaO) dan kombinasi antara abu kayu dan kapur (CaO). Dari hasil pengujian, kuat tekan bebas (UCS) semakin meningkat seiring bertambahnya waktu pemeraman, namun regangannya berbanding terbalik nilainya semakin kecil, hal ini dikarenakan pada kondisi awal pemeraman, tanah masih dalam kondisi seperti semula dan bersifat lunak, semakin lama tanah akan mengalami pengeringan sedikit demi sedikit dan menjadikan tanah tersebut menjadi lebih getas. Proses perendaman tanah menyebabkan terjadinya penurunan nilai UCS yang besar, makin lama perendaman dilakukan semakin kecil nilai UCSnya. Nilai kuat tekan bebas tanah dipengaruhi oleh proses pencampuran, kadar air, persentase campuran dan lamanya pemeraman (curing).

Soft soil is a soil that has low shear strength. A construction which is built on soft soil usually faces some problems such as low bearing capacity and settlement. Pile foundation is used when a supported soil is located quite far from the surface so that the bearing capacity which can sustain the building has to rely on the skin friction. To obtain the higher pile bearing capacity, several modifications are made including the addition of fins on the pile. This research studies the behavior of finned piles, particulary the relationship between bearing capacity and settlement. Piles were modelled with one and two pair of fins with variations of fin's lengths of 0.50D, 0.75D, 1.0D, and 1.25D. Those piles using the Constant Rate of Penetration (CRP) method. The distances between fins also varies from 3D, 5D, to 7D. The interpretation of loading test data using the Terzaghi and Peck method then it was compared with empirical calculations using the Individual Bearing and Square Shear method.The loading test results show that the length and number of fins affect to bearing capacity of the pile. Piles with 1 (one) and 2 (two) fins are able to bearing greater loads than piles without fin. The largest pile bearing capacity occurs in pile models with fin length's of 1.25D and distance of 5D. The calculation which used the Individual Bearing method produces the value of bearing capacity which is relatively same to the Square Share method. The piles bearing capacity of the model test result is significantly different from the second calculation of the empirical method. The addition of the fins length is more dominant and it improves the piles bearing capacity if it is compared to the change of the distance between the fins.Keywords : Individual Bearing, length of fin pile, Spacing of Fin pile, Square shear

West Papua is an eastern part of Indonesia that has great potential for earthquakes. Eastern Indonesia's seismic activity was triggered by geographical conditions in three major earthquake paths, namely the zone of the confluence of the Pacific and Papua New Guinea plates, the Sorong fault line and the Tarera – Aiduna fault (Naryanto, 2019). Bintuni Bay is one of the regencies in West Papua Province, located between the south coast of Bird's Head and the coast of the Onin Peninsula, facing the Seram Sea off the west coast of Papua. The sorong fault is one of the active faults (faults) of the earthquake source in the Bintuni Bay area (Ciptakarya.pu, 2002). Liquefaction is one of the failures in the soil structure that can occur due to cyclic loads or earthquake vibrations. Liquefaction is the event of the transformation of noncohesive soil material from solid to liquid properties due to an increase in pore water pressure in the soil cavity. The liquefaction potential was analyzed using the boulanger Idriss method (2014). This method compares the value of CSR (Cyclic Stress Ratio) with CRR (Cyclic Resistance Ratio). The factor of safety value (FS) is used as a limit for potential liquefaction or not. If FS > 1 indicates that the soil layer has no potential for liquefaction, whereas if FS < 1 indicates a potential soil layer of liquefaction. The results of the analysis showed that the magnitude of ≥ 5,6 Mw with soil acceleration (amax) ≥ 0,16 g has the potential to reduce liquefaction with very low to very high categories. Coastal areas have a higher liquefaction potential than land areas.

Permeability is the ability of a soil to allow liquids to pass through. Of course the soil has a physical characteristic that can be known by laboratory testing. This study aims to determine the physical properties that most affect the coefficient of cohesive soil permeability using the Artificial Neural Network (ANN) tool, the results obtained will later be matched with actual conditions according to the context of engineering geology. The research method begins with an influence or sensitivity analysis using ANN which will produce a correlation coefficient (R). Then, these results will be compared with the influence analysis based on the value of the coefficient of determination (R2). After that, accuracy and error tests will be carried out using the Mean Absolute Percentage Error (MAPE), the highest accuracy values is categorized as the most influential physical property of the 7 physical property parameters, namely liquid limit, plastic limit, plasticity index, %sand, %fines, %silt, and %clay. Based on the result of the analysis, %fines is the parameter that most influences permeability and is able to make very strong predictions with an R value using an ANN of 0.9941875, an R2 value of 0.6336, an accuracy of 99.6962%, and a MAPE of 0.3038%. These results are compared with the existing empirical equations with an accuracy of 96.4393% and MAPE of 3.5607%. It can be concluded that ANN is more effective and optimal in making predictions. In this case, in the context of engineering geology, the more %fines, the smaller the permeability coefficient of the soil.

Tanah gambut merupakan tanah dengan kadar air serta kadar organik yang tinggi. Hal ini menyebabkan tanah gambut memiliki tingkat kompresibilitas dan penurunan yang tinggi serta daya dukung yang rendah. Atas dasar permasalahan itulah, timbul alternatif untuk menggunakan tiang helikal yang dapat meningkatkan nilai daya dukung tanah gambut. ini. Selain itu, tanah akan selalu mengalami tahapan rangkak yang jika berlangsung dalam waktu lama akan memiliki nilai penurunan yang signifikan dan menjadi berbahaya jika tidak diperhitungkan dengan baik. Penelitian ini bertujuan untuk menyelidiki pengaruh parameter rangkak (creep) terhadap penurunan tanah dan pola keruntuhannya. Penelitian dilakukan dengan memodelkan tiang helikal dan tanah gambut menggunakan aplikasi PLAXIS 2D dengan menggunakan model material Soft Soil Creep dan Soft Soil. Pemodelan tersebuat dimodifikasi dengan pemberian variasi parameter indeks rangkak/creep index (Cα) yang berbeda, mulai dari Cc/30 hingga Cc/10. Hasil pemodelan dengan menggunakan parameter indeks rangkak yang berbeda menunjukkan nilai penurunan yang semakin besar seiring dengan nilai indeks rangkak yang meningkat. Efek rangkak sendiri akan terlihat jelas mulai dari simulasi konsolidasi 1 tahun hingga 10 tahun. Hal ini disimpulkan setelah membandingkan pemodelan dengan model menggunakan material Soft Soil Creep dengan Soft Soil, dimana terlihat penurunan akan terus berlangsung setelah konsolidasi 1 tahun pada material tanah Soft Soil Creep yang menggunakan parameter Cα, sementara pada material tanah Soft Soil penurunan sudah tidak berlangsung lagi setelah 1 tahun konsolidasi.

The use of helical foundations to support structures on peat soil is still a new method. Research is needed to develop this foundation. There are 6 types of helical foundation tested on peat soil. To study the effect of helical plate diameter, plate diameters were varied with sizes 25 cm (M), 35 cm (L), and 45 cm (G). Plate positions (1, 2, 3 plates) are designed at 300 mm spacing. The axial compression bearing capacity test is carried out based on the constant rate of penetration procedure. At the beginning of loading, the load increases significantly. At a certain descent, the load begins to decrease slowly. The load-settlement curve shows that the larger the plate diameter, the greater the load it can withstand. The largest bearing capacity is produced by the GGG 30 foundation (3 plates dia.45 cm), which is 10.83 kN. LLL 30 helical foundation (3 plates dia.30 cm) provides a bearing capacity of 7.14 kN. These results clearly explain that the increase in plate diameter is directly proportional to the increase in the axial compression bearing capacity.
